# Zephyr build system imposes to have a fixed folder structure for the target-specific
# files, that is [...]/boards/ARCH/BOARDNAME because it infers the target
# architecture by looking at the name of the parent folder of the board folder.
#
# This does not make sense, because:
# 1) The folder with the target-specific files should be put anywhere, given that
#    the project using Zephyr may have its own conventions.
# 2) Inferring the target architecture only from the folder tree is an idiocy.
#
# So: to make Zephyr play happily in his sandpit without complaints, we create a
# board_root subfolder inside the build one and we copy the board-specific config
# files there from our platform/targets tree creating the necessary folder tree.
#
# NOTE: the board-specific CMakeLists.txt files have to use the ${OPENRTX_ROOT}
# variable as the base path. E.g. ${OPENRTX_ROOT}/platform/drivers/somedriver.c
#
